Graphite Glass Marble Sphere Mold

The graphite glass marble sphere mold is a specialized tool engineered for artisanal glass crafting, tailored to shape molten glass into precise, smooth spheres during lampworking and glass blowing. Made of high-purity, dense graphite via precision machining, it delivers consistent performance for glass casting art.

Key traits include exceptional thermal conductivity—ensuring gradual, uniform cooling to prevent glass cracking—and a non-stick surface that avoids adhesion, preserving the marble’s flawless finish. Its robust thermal shock resistance withstands abrupt temperature shifts from molten glass contact, ensuring durability.

Ideal for independent glass artists, studio crafters, and educational workshops creating custom marbles, decorative glass spheres, or small sculptural components. Far superior to ceramic alternatives, it offers reusable reliability, customizable sphere diameters (10–50mm typical), and minimal maintenance, elevating precision and efficiency in glass art creation.
